The last pic focuses in on Jenner's cleavage as she grabs her breasts.

It seems Jenner's shoot might be for more than just fun -- the Kylie Lip Kit creator linked to a new Instagram, @kyliejennershop, which many speculate is related to her upcoming Kylie Cosmetics pop-up shop, set to open on Dec. 9 at the Westfield Topanga mall in Canoga Park, California. Jenner also teased the photo shoot on Instagram in September, crediting her own makeup line for her beauty looks.
